Mark Henderson’s book “The Geek Manifesto” was part of my holiday reading, and there’s a lot to like in it – there’s all too much stupidity in public life, and anything that skewers a few of the more egregious recent examples of this in such a well-written and well-informed way must be welcomed. There is a fundamental lack of seriousness in our public discourse, a lack of respect for evidence, a lack of critical thinking. But to set against many excellent points of detail, the book is built around one big idea, and it’s that idea that I’m less keen on. This is the argument – implicit in the title – that we should try to construct some kind of identity politics based around those of us who self-identify as being interested in and informed about science – the “geeks”. I’m not sure that this is possible, but even if it was, I think it would be bad for science and bad for politics. This isn’t to say that public life wouldn’t be better if more people with a scientific outlook had a higher profile. One very unwelcome feature of public debate is the prevalence of wishful thinking. Comfortable beliefs that fit into people’s broader world-views do need critical examination, and this often needs the insights of science, particularly the discipline that comes from seeing whether the numbers add up. But science isn’t the only source of the insights needed for critical thinking, and scientists can have some surprising blind-spots, not just about the political, social and economic realities of life, but also about technical issues outside their own fields of interest.
